The Diaoyu/Senkaku Islands: A Japanese Scholar Responds
By TAKAYUKI NISHI
The People’s Republic of China’s claim that the Senkaku/Diaoyu Islands are an “inherent territory” of China contradicts its own demands before 1970.
Before 1970, the People’s Republic of China did not merely acquiesce to Japanese sovereignty over the Senkaku/Diaoyu Islands. China demanded self-determination for the U.S.-administered Ryukyu Islands, with an option of return to Japanese administration, while specifically including the “Senkaku Islands”. Thus, China agreed with the United States and Japan that, in the event of the Ryukyu Islands’ return to Japanese administration, the United States should also return the Senkaku Islands to Japan.
...
The second paragraph is a false statement. Thus all that follows doesn't have ground to stand.
Post WWII international order is mainly established upon the Cario Declaration (see [Cairo Communiqué](Text) | Birth of the Constitution of Japan) and the Potsdam Declaration .
A 1785 Japanese map, the Sangoku Tsūran Zusetsu (三国通覧図説 by Hayashi Shihei adopted the Chinese kanji (釣魚臺 Diaoyutai) to annotate the Senkaku Islands, which were painted in the same color as China.[11][16] The primary text itself can be found here.[17] - wiki
Thus Diayu Island is an occupied land by Japan in WWII. It should be return to China.
The Potsdam declaration also specifies that:
(8) The terms of the Cairo declaration shall be carried out and Japanese sovereignty shall be limited to the islands of Honshu, Hokkaido, Kyushu, Shikoku and such minor islands as we determine.
Thus Japan does not have sovereignty over Ryukyu Islands. Unless it wants to subvert post WWII world order.
This Japanese guy's saying that if China doesn't make noise before 1970 means China yields the sovereign on Diaoyu Islands to Japan. This funny guy forgets a common sense. He believes if a thief steals something the victim must claim before certain time frame, or the steal is legal.
BTW, even since June 1971, when US signed Treaty of "Reversion to Japan of the Ryukyu and Daito Islands" with Japan in Washington, flying Japanese flag in Ryukyu is considered criminal upto today... and let's not forget PRC's "An Declaration of The Ministry of Foreign Affairs of the People's Republic of China, 1971-12-30" to dispute Diaoyu Islands shortly after the handover of Ryukyu.
